  1. 1. Alpha-class glutathione transferases as steroid isomerases and scaffolds for protein redesign

    Författare :Pär L. Pettersson; Roberta F. Colman; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biochemistry; Biokemi; Biochemistry; Biokemi; Biokemi; Biochemistry;

    Sammanfattning : The present work focuses on the glutathione transferase (GST) Alpha-class enzymes, their characteristics as steroid isomerases and structural plasticity as malleable scaffolds for protein design. The GSTs are a family of detoxication enzymes that appears to have a wider variety of additional functions. LÄS MER

  3. 2. Countercurrent operation in the dilute-acid hydrolysis of cellulose for ethanol production

    Författare :Pär Pettersson; Avdelningen för kemiteknik; []

    Sammanfattning : Fuel ethanol can be produced from lignocellulosic materials to replace gasoline and diesel. A crucial step in the production process is the hydrolysis (saccharification) of the material, which can be achieved with dilute acid at high temperature. Unfortunately, sugar is degraded under these severe conditions, and the sugar yield is generally low. LÄS MER
